Abstract: A vehicle folding top is stowed in an associated generally U-shaped folding-top box when the folding top is opened. The folding-top covering held by a folding-top structure is, during the lowering of the folding top, drawn into the folding-top box while, at the same time, run on a directing edge at the upper margin of a limiting wall of the folding top box. The directing edge extends over a middle wall and over a part length of the side walls of the folding-top box and is softened by rounding edges which merge into the wall surfaces. To allow the folding-top covering to be inserted into the folding-top box with a minimum of wear, an additional directing contour is provided above the box and comprises, at its upper margin, a run-on edge set back relative to the directing edge of the folding-top box and a sliding surface located between the directing edge and the run-on edge.

Abstract: An actuating device is provided for closing and opening a door or lid lock and correspondingly switching a light on and off during the opening and closing of the door or lid. This actuating device also makes it possible to switch off the light permanently when the door or lid is open, because the switch is switchable indirectly per se as a result of movements of a rotary latch and can be switched manually into its switch-off position independently of the actuating device.

Abstract: An intermediate folding top bow is fastened, via cantilevers arranged at its ends, to lateral roof-frame parts of a vehicle folding-top structure. During the opening operation of the folding-top structure, the intermediate bow is pivotable out of a tensioning position directed forwardly into a stowage position directed rearwardly. To make it possible to ensure that the intermediate bow will be stowed automatically and without being damaged, the intermediate bow is loaded during the opening of the folding top with a pivoting effect by a separate working element so that starting from its tensioning position, the intermediate bow is driven beyond a dead center between its tensioning position and its stowage position.

Abstract: A safety device for motor vehicles is in the form of an air bag located on the driver side and on the front-seat passenger side to prevent a vehicle occupant from colliding with front interior parts of the passenger compartments. The two filled air bags overlap one another in the middle region of the vehicle land, as seen in a top view, are each designed with a mutual bearing face extending at an angle relative to a transverse axis of the vehicle, thereby preventing an occupant from slipping through between the two air bags.

Abstract: A process and apparatus for influencing a central locking system (CLS) in a motor vehicle wherein a separate release of a driver-door closure is provided and wherein, without special preselection measures in the vehicle interior, a vehicle user can, during each release at the locking station assigned to this closure, decide whether he wants to release only this one closure separately, by actuating the corresponding locking station once, or whether he wants to release the closures of the vehicle centrally, by actuating this locking station twice.

Abstract: Divided flywheel arrangements having a spring arrangement, and preferably also a slip clutch arrangement, accommodated in a lubricant bath, which is formed by an annular space limited radially outwards only by parts which are stationary relative to one another. Centrifugal forces acting on the lubricant cannot therefore force the lubricant against seals between mutually movable parts. Certain disclosed arrangements do not accommodate these parts in a lubricant bath.

Abstract: A servo control for power-assisted steering for motor vehicles having two coaxial shaft parts that are positively coupled to each other, but with play. The shaft parts are coupled such that limited relative rotations between these shaft parts are possible against the resistance of a pretensioned spring arranged in between. These relative rotations cause a pivoting stroke of a lever arranged between the shaft parts, this lever thereby actuating the control spool of a servo valve.

Abstract: A method for controlling propulsion in motor vehicles is described which detects when the vehicle approaches the limiting value for lateral acceleration independently of the condition of the load, the tires, the roadway and so forth in that a measurement value for the lateral acceleration, the yaw velocity or the difference of the front wheel speeds of rotation is compared with a mathematical value determined by the use of a mathematical formula, in which method this mathematical value is phase-delayed in a filter and corrected in a first correction unit and the mathematical formula used is corrected in a second correction unit.

Abstract: A drive-slip control device (ASR) for a road vehicle also equipped with an anti-lock system (ABS) that works on the return-flow principle. The ASR works on the principle of decelerating a vehicle wheel tending to spin by subjecting its wheel brake to pressure. During the drive-slip control mode, the return pump of the ABS, has its inlet supply take place via a precharging pump as an auxiliary-pressure source. By an ASR control valve, the affected brake unit can be shut off from the main brake line of the brake circuit of the driven vehicle wheels. A valve arrangement, which is activatable by the output pressure of the precharging pump is provided to connect the outlet non-return valve of the precharging pump, and the ASR outlet valve (connected between the brake-fluid reservoir and the return line) to a pressure-medium line subjected to brake pressure for normal braking.

Abstract: In a process for regulating the fuel/air ratio in internal combustion engines having an exhaust gas measuring probe and a catalyst, the fuel/air mixture fed to the internal combustion engine via a proportioning device being regulated to a virtually stoichiometric value in a control unit with variable characteristics as a function of the exhaust gas composition detected by the measuring probe, the characteristics of the control unit are variable in dependence on the operating time of the catalyst.

Abstract: In a brake apparatus for a hydraulic two-circuit brake installation of a road vehicle with static brake circuits, an outlet pressure space is provided for one of these brake circuits in which the brake pressure that is coupled into a static brake circuit of the vehicle, is adapted to be built up by the displacement in the same direction of a master cylinder piston which is also displaceable by the pedal force alone, and of a servo piston which is displaceable only when the brake force servo unit is intact.

Abstract: A safety device in the form of an airbag for motor vehicles is disclosed wherein, from a specified vehicle deceleration onwards, the airbag is located inflated in front of a vehicle occupant. The airbag has outlet openings in its cover which permit the gas volume to be partially forced out, the airbag resting with a support surface against a curved windscreen surface and having on its opposite side an impact surface for the vehicle occupant when inflated. The impact surface is approximately aligned in the vehicle transverse direction. The outlet openings have an enlarged opening cross-section for the emergence of gas near to a greatest curvature region of the windscreen surface in relation to a vehicle transverse axis. As a result of this enlarged opening cross-section, the airbag is purposefully more strongly compressed in this region on being impacted by a vehicle occupant.

Abstract: An internal combustion engine has a catalytic converter in its exhaust gas path. In the catalytic converter, two exhaust gas emission measuring probes are provided spatially separated from one another. The phase shift between the output signals of these two measuring probes is used as a measure of the aging of the catalytic converter.

Abstract: The invention is a passenger compartment heating system for a bus heating system having a closed circuit through which there flows a heat transfer medium. A heat exchanger which is fed on the primary side by a heat-generating unit is used as heat-absorbing part. The inlet temperature and the heat transfer medium are matched to one another in such a way that there is a two-phase liquid/vapor mixture in the passenger heaters, which are arranged in series. The heat exchanger is designed as a capillary block or as a capillary-active porous wall into which the heat is fed on the primary side. The porous wall furthermore divides the vapor-only side from the liquid-only side of the closed circuit of the passenger compartment heating system and, in this region, has virtually only capillary-active channels.

Abstract: A wheel suspension for vehicles comprises for each wheel a wheel control arm, which is pivotally movable against the torsional force exerted by a torsion bar. The torsion bar extends transversely to the wheel control arm and is fixed against rotation at a distance from the wheel. In order to reduce the manufacturing costs and the weight of the wheel suspension, the wheel control arm and the torsion bar are integrally combined in an L-shaped component, which is provided adjacent to its apex with a pivotal mounting, which together with mounting for non-rotatably fixing a free end of the torsion bar defines a pivotal axis for the wheel control arm.

Abstract: A liquid friction coupling comprises a housing that contains a viscous liquid, a shaft protruding into said housing, alternating and interdigitating inner and outer blades, which are axially slidably and non-rotatably connected to the shaft and to the housing, respectively, annular expanding springs, which extend between adjacent inner blades or outer blades, and an annular piston, which is sealed in the housing and axially displaceable therein and is operable from the outside and arranged to act on the blades in order to change the blade spacing. In order to increase the range in which the blade spacing can be controlled and possibly to permit the coupling to be used as a clutch coupling, the volume of the viscous liquid which is contained in the housing equals the total volume of the free spaces in the housing outside the outer periphery of the inner blades when the piston is in the position which corresponds to the largest blade spacing.

Abstract: A device for locking an actuating lever of a shifting device of a gear-change mechanism of a motor vehicle, in a lever position associated with a particular shift state utilizes a swivellable locking element connected to a brake pedal via an adjusting linkage to be moved into a locking position by a restoring spring holding the brake pedal in the unactuated rest position. Depression of the brake pedal releases the actuating lever. The adjusting linkage contains a resiliently-acting intermediate member acting on the locking element control to position a counter-control cam into engagement with an actuator control cam to lock the actuator. When the actuating lever is actuated into a nonlockable lever position, the locking element is moved into a floating position against the spring force of the intermediate member, while the brake pedal remains essentially in a rest position by virtue of an enlargement of the effective length of the adjusting linkage.

Abstract: A drive-slip braking control device (ASR) for a road vehicle equipped with an anti-lock system (ABS) and having a hydraulic dual-circuit brake system, in which, on the brake circuit (II) of the driven vehicle wheels, the ABS works on the return-flow principle and the ASR on the principle of decelerating a vehicle wheel tending to spin by subjecting its wheel brake to pressure from an auxiliary-pressure source. A return pump of the ABS (assigned to the brake circuit of the driven vehicle wheels) is utilized as an auxiliary-pressure source for the drive-slip control mode. The brake unit can be shut off from the main brake line of the brake circuit of the driven vehicle wheels by an ASR control valve. The brake fluid supply flow path leading from the brake-fluid reservoir of the brake system to the inlet side of the return pump of the brake circuit of the driven wheel is one of the compensating flow paths of the brake unit.

Abstract: An arrangement is disclosed for improving the seam strength of plastic containers produced by coextrusion blow-molding which are provided with a diffusion barrier layer incompatible with the base material. To improve the seam strength, the same is therefore designed as a web seam which is folded in labyrinthal shape and the folds of which are welded to each other. The length of the web seam in the unfolded state is equivalent to at least three times the thickness of the coextrudate and the web seam is folded at least doubly.

Abstract: The invention relates to a device for angularly adjusting an internal combustion engine camshaft in relation to a crankshaft and comprises an adjusting bushing connected to the camshaft, with an input sleeve surrounding said bushing, and with an actuator displaceably arranged there between. An input sleeve, the actuator, and the adjusting bushing are each provided with helical gear teeth to translate axial shifting of the actuator into relative rotation between the camshaft and crankshaft. In order to prevent rattling noises in the gear teeth that are caused by changing moments in the drive of the camshaft, the actuator is guided in stop-free fashion. A stop, which is effective between the input sleeve and camshaft, limits the angular adjustment so that the actuator is stressed between the input sleeve and camshaft to avoid backlash during rattling.
